Daily Chess Improvement: Middlegame Tactic!

And then there's the idea 1...R:g2+ 2. K:g2 Rg8+ 3. Bg6 Qe7!! with the idea that 4. Q:e7 leads to mate in 3.

Yes, it is bit harder to develop any counterplay as white in the 1. ....Be5 lines simply because the material is exchanged down to a single rook for white pretty much by force. I would also feel more comfortable in those positions. However, I do admit that the material edge isn't all that much different- objectively it seems to me that 1. ...Rxg2 leads to a somewhat larger edge as even in the 3.Bg6 line, but just barely by my count.

Dave, 3.Bg6 Rxg6+ 4.Qxg6 hxg6
I don't feel comfortable to play such endgame.
I like these varirions. It's easier to play these endgames for me.
