On the bright side, Richie really impressed me with his tactical alertness. Here are two interesting moments that featured themes we had recently practiced.
Position #1.
This first one is pretty elementary once you look around at the whole board. Richie is up material but his opponent has the simple threat of c2 followed by c1=Q. What's the most easiest way for Richie to wrap up the victory?

Highlight below to reveal answer:
Richie played Ba5! Black cannot defend against the double threat to win the pawn and mate on the backrow. Note that Bxf6 is worse because it opens an escape square after gxf.
Position #2
Richie's opponent dropped a pawn early in this game but turned things around by making use of the open lines/diagonals vacated by the lost pawn to launch a severe attack. Richie attempts to hold his position together with duct-tape and string but he senses his imminent demise. The position calls for a major swindle so Richie responds with the mysterious Bc8?!, inviting his opponent to increase the pressure with f6. After all if the position is a win now, it's definitely a win with the pawn on f6 right?

Highlight below to reveal the missed win, and Richie's devastating counter-attack. Had his opponent followed Richie's camp coach's advice to always analyze the forcing moves in the position, he could have found the winning attack or at the very least, discovered uncovered Richie's trap before it was too late:
His opponent misses the forcing line: Bxg7+, BxBg7, Rh3+, Nh2, RxNh2+, f6+, Bf5, Qg7#. Instead the attack on the f-pawn provoked the seemingly strong f6??. How can opening up the diagonal for the bishop bringing the pawn closer to the enemy king be a bad move? No doubt, his opponent counted on something like gxh??, Qg7# or gxf?? Qg7#, or maybe just Bxf6, where he thought Rxf6 would be good enough in view of gxf6? Qg7#.
Instead, after f6??, Richie surprised his opponent with Qxf3!!, after gxQf3 (forced) comes the cute Bh3#.
What impressed me the most about this was the "trapiness" of the move. Richie realizes he's lost but plans this tricky mate with his move Bc8. From the diagrammed position he had to visualize the removal of the pawn on f5, the distraction of the pawn on g2 via queen sac, and the two bishop's mating motif.
Of course we'd prefer to not get into losing positions in the first place, but having the resourcefulness to turn things around by inducing non-obvious blunders is a valuable skill to have as well.
