More 10x8 mating problems

Introduction

This a my second set of five mating problems for the various 10x8 Chess variants out there with the Rook + Knight and Bishop + Knight pieces. Solutions (hidden via CSS) are at the bottom of the page.

The following positions are not composed problems, but are positions from actual games played with my own 10x8 Chess variant.

Setup


Position 1:


Black to move and force mate


Position 2:


White to move and force mate


Position 3:


Black to move and force mate


Position 4:

Position 5:

Pieces

All of the FIDE Chess pieces, with a Rook + Knight and Bishop + Knight piece added. Just as the Queen is a Rook + Bishop piece, there is a Rook + Knight and Bishop + Knight piece in these positions. In the solutions, the "A" represents the Knight + Bishop piece, and the "M" represents the Rook + Knight piece.

Rules
