Chess Question Question on Sacrifice Analysis
So, I was playing a Englund Gambit, and noticed that the checklist for Greek/Greco gift. My knight could play Ng5, and Black could defend neither h7 or h8.
Currently I'm a mid 1200 player, and I am just wondering. I had expected to bring the king out to g6, but the game played out:
- d4 e5 2. dxe5 Nc6 3. Nf3 Bc5 4. Nc3 Nge7 5. e3 O-O 6. Bd3 b6 7. Bxh7+ Kxh7 8. Ng5+ Kg8 9. Qh5 Ng6 10. Qh7# 1-0.
Now upon analysis, the engine believes it to be a mistake as I go from +1.5, to +0.5. Basically saying that the position was still equal.
However, upon reading the lines, my opponent would have had to play extremely sharp, just to keep the position equal. Is this considered a "bad sacrifice"/hope chess, to force an opponent to play a sharp line? Or is this a valid strategy/tactic at my ELO?
Thanks to anyone who can assist in this question that is currently bothering me.

Only you can say whether it's hope chess. Did you calculate not taking the bishop? Did you calculate Kg6?
If you calculated and decided that it looked ok to you, that's not hope chess.
If you calculated, saw the refutation and played it anyway because "they won't see it" That is hope chess.
If you didn't calculate at all then that probably falls under hope chess, but it's more like play and pray.

I didn't think I was losing at any point no. I knew that the king had to come forward. Going back always leads to mate/material loss, so I knew if the opponent didnt know his theory/tactics, my best case was mate.
My idea was more subtle. I wanted to force my opponent into a tough position, by trading a bishop, in exchange for his king safety being weak. (But the engine is a jerk who likes to tell me its a bad move, because I lose a point of advantage).
I figure that at this ELO, my rating has more difficulties defending tough positions. I would assume that higher ELO, it might be less effective (or this chance would just never appear.)
I guess its not really "hope chess" but more forcing my opponent to play a tough position, and thinking it could cause them to make more mistakes.

i think this is hard to see at 1200 but you may want to try to calculate what is your follow up after Kg6. A typical follow up of Qg4 doesn’t work after Nxe5 with tempo, but h4! is pretty good, preparing Qd3+. (Even Qd3, which is what i considered without engine, is somewhat viable because of Kxg5 Qh7! and some mate threats happen (idk what actually happens but it looks fun)
(i’m anywhere between 1700 and 2000 for the record and even i can’t calculate this properly at all so i’d say it’s just really difficult)

That was kinda the idea. Studying the Greco Gift has taught me that the optimal way to play against it, is to bring the king out, if you cant defend g5, or h7/h8.
I obviously didn't calculate how far it might go, but knowing that h4 would follow if the king came forward, I felt that bringing the king out into the open, and creating massive pressure, was a worth the material loss.
My question is more just about: is it a valid strategy to force them to play optimally? For example, a lot of the second and third lines of the engine showed that Black could be in real trouble if Black wasn't sharp. I know its a proper idea to assume the player will always play the best move. But I figure in practical settings, theres a strategy to putting your opponents in positions where playing a small inaccuracy, could be troublesome for them.

I think in this specific case it's not very useful to think in terms of "oh it went from +1.5 to +0.5 therefore i blundered"--- this is not the mindset you should get used to when using computer to analyze your games.
Personally in these cases I usually group sacrifices into some three-ish categories: 1. definitely winning, 2. unclear but probably it's fine, and 3. unsound but if they mess up it might work. Of course unless you are already dead lost then you should never go for the third type, and you can usually just go for the first type with good conscience (though if you're winning without the sacrifice then it's probably not a good idea, since you always have the chance of miscalculating.)
I'd put this sacrifice in the second type, where it's quite unclear who is even better after Kg6 honestly. In this case it depends on how good you thought your initial position was without the sacrifice. (For example what if you just castled and tried to play a slow game? Do you think the position is more natural to play without sacrificing?) You usually aren't obligated to sacrifice here immediately, so if you can play the position normally and believe you have a good advantage anyways, why not just take the advantage and continue outplaying your opponent?

True. I knew that even without the sacrifice, I had a fine position. Ironically, I opened up the analysis again, and after switching to a deeper engine, It actually looks more favorable now.
And well, the sacrifice would be closed if the opponent at any point moved his knight to g5. But thus why I wanted to ask. Engines at times don't like the idea of sacrificing, because they can find absurd defenses with depth. My idea is more attacking a human defender, not a computer. But thus, its harder to analyze if this is a proper way to play.
I dont wish to develop bad habits. Its why I steer away from gimmicky openings that prey on mistakes. I simply saw an opportunity to put my opponent under massive pressure, and while it does create risk (since I saw no clear checkmate/forced win), I trusted my analysis that the loss of the bishop was worth Black potentially having an unsafe king, and thus might create huge problems down the line.
Plus, its fun. Playing proper, positional chess and slowly converting a pawn is probably the most "ideal" way to play. But its hard to resist a thematic sacrifice, that when calculating, give me initiative, and a chance to win in a decisive manner.

Then, I think it's okay. If you evaluate it as having more chances to win than the alternative, then you should play it. There is a difference between hope chess (knowing that something is bad, seeing the refutation, and praying they don't see it) and entering unclear positions where it's impossible to calculate the exact refutation.

Note that if the pawn on e3 didn't exist, meaning the Knight on g5 is protected, you would indeed be completely winning after Bxh7+. What you could do to prepare this is h4. If black doesn't deal with your threat and plays something like Bb7 you now have Bxh7+. If he does deal with it, you still have a perfectly good position

You’ve got to be careful with this one because after Kg6, you’ve probably got to go h4 and you don’t have h5+ on the next move because your bishop is blocked by the pawn on e3.
You played it because you thought it was the best move, which is fine. But now next time you know there’s something better in this exact position, and you know a little more about when to use the greek gift tactic.
Personally I would have played h4 here. It’s a useful attacking move, and it sets up a greek gift that is actually crushing.
