Monster chess

Yeah I thought I could always take the pawn later, and it is better to solidify my position and prepare a mating net first.
Qd6

Instead of Qd6, which was an obvious blunder, Qh3 was much better, and Black should have been just winning.

With best play - Black wins. There exists a single plan by Black that wins, otherwise, as in the previous game, White was winning. Good to know ALL the standard rules, and agreed upon ... such as K X K Wins for White. meaning if within 1 square of the Black King and on the move, it's checkmate K X K.

Monster chess was one of the 1st variants, along with bughouse. Some played losers, Kings could not be captured, checks enforced, whole different game than todays versions.
